Hyperapp-debug NPM

Hyperapp Debug

A debugger for your Hyperapp applications.

What is it

hyperapp-debug is a debugger for your hyperapp development flow. It gives you insight into state transitions, when effects are fired, or if you have stubborn subscriptions.

Hyperapp V1

If you are debugging Hyperapp V1 applications, check out the legacy debugger.

Installation

Install with npm or Yarn.

Then with a module bundler like Rollup or Webpack, use as you would anything else.

import { app, h } from 'hyperapp';
import { debuggable } from 'hyperapp-debug';

Or with <script type="module"> and unpkg:

import { app, h } from 'https://unpkg.com/hyperapp?module=1';
import { debuggable } from 'https://unpkg.com/hyperapp-debug?module=1';

If you don't want to set up a build environment, you can download Hyperapp Debug from a CDN like unpkg.com, and it will be globally available through the window'hyperapp-debug'.default object. hyperapp-debug supports all ES5-compliant browsers, including Internet Explorer 10 and above.

<head>
  <script src="https://unpkg.com/hyperapp"></script>
  <script src="https://unpkg.com/hyperapp-debug"></script>
</head>
<body>
  <script>
    const { app, h } = window.hyperapp;
    const { debuggable } = window['hyperapp-debug'];
    // Your code here...
  </script>
</body>

Usage

Use debuggable to wrap Hyperapp's app function.

import { app } from 'hyperapp';
import { debuggable, adapters } from 'hyperapp-debug';

debuggable(app)({
  init: {},
  view: () => null,
  subscriptions: () => [],
  node: document.getElementById('your-app'),
  debug: {
    enable: true,
    adapter: adapters.ConsoleAdapter.use,
    id: 'your-custom-id',
  },
});
